     본 발명은 조루를 방지하기 위한 콘돔제조에 관한 것입니다                     (나)해결하고자 하는 과제 
     기존에 조루 방지 콘돔이 콘돔의 두께를 두껍게 하여 자극을 줄이려는 시도        를 하였으나 콘돔 안에서 남 성기의 미끄러짐이 오히려 사정을 촉진할 수 있       다는 생각이 들었고 또한 국소마취제가 들어간 콘돔은 사정을 억제할 수는         있지만 사정 후의 이물감이나 잔뇨감으로 인해 오히려 불쾌할 수도 있겠다          싶었습니다  
     (다)과제의 해결수단 
             본 발명은 조루를 방지하고 부부관계를 정상적으로 유지하기 위한 콘돔에         관련된 고안이다 
           여러 해 전에 콘돔이 불편하던 생각이 난다 콘돔이 어떤 면에 서는 조루에 
            조금 효과가 있을 수도 있다 하지만 그것은 단편적인 생각 아마 그 효과는 
           겉을 조금 싸준다는 것이지만 오히려 미끄러운 표면을 생각 안 한 것이다 
          아무리 두꺼운 보형물에 쌓여있어도 안에서 성기가 미끄러지는 것을 생각하면 
          그것은 아무 효과를 낼 수가 없다 그 이유는 콘돔 안에서의 윤활효과를 
          간과한 것이다 콘돔이 아무리 두껍게 만들어도 흥분한 상태에서 성기에서 
           나오는 윤활성분의 액체나 땀을 생각 안 한 것이다 콘돔 안에서 움직이고 자         극 받게 되면 조루에는 아무 효과가 없는 것이다 즉 여성생식기와 접촉을 막        을 수는 있지만 콘돔 안에서의 움직임과 자극은 어쩔 수 없는 것 콘돔 안에         마취제를 넣어 조루를 
            막아 보려했지만 그것도 역시 불쾌감이나 사정 후의 이물감등 조루를               막을 수는 없는 것 그 문제를 해결하려면 콘돔의 두께가 문제가 아니라 
             콘돔 안에 서의 미끄러지는 자극을 없애는 것뿐이다. 
             콘돔 안에 스타킹 원단을 비롯한 모든 신축성 있는 원단을 붙인다 여기 필         수적인 것은 남성기는 자극에 취약하므로 부드러운 원단이 필수적이다   
           이렇게 콘돔과 결합하여 콘돔 안에 있는 성기의 움직임을 어느 정도 잡아줄       수가 있다면 보다 효과적으로 조루를 막는 효과를 볼 수 있으리라 생각난다 
            (라) 효과 
     현재 전세계에서 팔리는 콘돔은 일 년에 수억 개이며 이 중에 특수목적이나        취향에 맞는 여러 가지 콘돔이 출시되고 있으며 지금의 이 스타콘돔(가칭)도        여러 사람 특히 조루로 인해서 성생활에 자신 없고 심각한 콤플렉스에 빠진          남성들이 많은 이용 있을 것으로 생각되어 진다.
